Transportation Engineering

SEI’s transportation engineers provide a full package of services to take roadway and intersection projects from concept to completion. Registered and experienced, they offer quality management and technical expertise in transportation planning that covers all types of roadways and all phases of construction and implementation – whether it’s for improving intersections, widening existing roads or building new ones.

Every SEI transportation design project is preceded by in-house surveying and supported by SEI traffic engineering services. Their aim is to make roadway plans buildable, cost-effective, safe and efficient for public use. For this reason, most transportation projects stay completely in house. This minimizes time spent on coordinating, and shifts the emphasis to quality control and customer satisfaction.

Using the latest CADD/GIS modeling techniques, SEI’s transportation engineers identify community and policy issues, then work with the public and clients to determine the best solutions.
